The Green Bay Packers' corporate backers purchased the remaining seats at Lambeau Field to avoid the first local blackout in three decades.

The weather forecast for fans who will attend (or play in) Sunday's wild-card game between the Packers and the San Francisco 49ers, however, remains about the same.

It'll be cold. Crazy cold.

It's expected be near zero at the 4:40 pm ET kickoff with a wind chill that could make it feel like minus-20. The temps are expected to drop minus-5 with a wind chill of minus-30 by the end of the game.

Sunday's game could place it among the top three most frigid games in NFL history. The second-coldest in terms of wind-chill factor was the 1982 so-called Freezer Bowl between the San Diego Chargers and Cincinnati Bengals.The game had an average temperature of minus-6.5 with a wind chill of minus-32.

But at least the Packers' beer taps won't freeze and workers have cleared out the ice/snow in the stands.
